My 2001 Sentra GXE has 101,000 miles & its time to change the Plugs. I already bought 4 NGK PLFR5A-11 Double PLatinum plugs. Does anyone know what the torque specs are? And do these plugs really take a 16mm or 5/8" Thanks.

It's 25 ft. lbs. in my 2003 Sentra. Is this the first time changing them? I hope they come out easy. I changed my factory ones at 50K miles and they were a pain. Changing them at 100K miles was much easier when I torqued them to 25 ft. lbs. and applied the right amount of di-electric grease to the threads. I tried changing my sister-in-laws plugs in her 03 Sentra at 50K miles and one was siezed tight.....she decided not to take it to the dealership to have it replaced.
